If you want to see some flat out incredible optics, don't buy until you've looked through some Fujinons. These are the guys who make a lot of medical optics (microscopes, endoscopes, etc.). I looked through a pair of their rubber armoured 7x50 Marine binoculars, and reached for my wallet without laying them back on the counter. I've used a lot of great stuff over the years, but after 25 years of baking, freezing, and getting used hard, they're as sharp and crisp as ever. They're at least the equal of Zeiss and/or Leica, and half the price.
